16 year old Eswar Anandapadmanaban has developed a wireless respiratory device for patients with breathing problems. Chosen as one of the top 15 global finalists in the Google Science Fair, Eswar's respiratoy monitor was inspired by the theremin's ability to sense proximity. Utilizing the same basic electronic principles, the device uses heterodyning oscillators to detect changes in breathing patterns by measuring the subtle rise and fall of the patient's chest. Dubbed the ThereNIM (Non-Invasive Monitor), the device never needs to make physical contact with a patient to track breathing patterns, eliminating the discomfort associated with current electrode-based monitors.
